September 15, 2008 The submarine was invented several hundred years before the automobile, but it’s not surprising that it is taking a little longer to reach ubiquitous recreational usage. A bent fender is small change indeed compared to the inconvenience of Decompression Sickness, asphyxiation or perhaps being crushed to death. The risk of such perils had to be comprehensively mitigated before recreational submarines could safely come to market and the Dutch U-Boat Worx was the first to get it all right with the C-Quester one-seater CQ1 and two-seater CQ2. Now the company is set to launch a completely revamped CQ2 aimed at the SuperYacht Market and a two-, three- and four-seater CQ3 (pictured) aimed at the tourism industry.
